This patch adds the ability to store extra field metadata in the table
map event. This data can include pack_length() or field_lenght() for
fields such as CHAR or VARCHAR enabling developers to add code that
can check for compatibilty between master and slave columns. More
importantly, the extra field metadata can be used to store data from the
master correctly should a VARCHAR field on the master be <= 255 bytes
while the same field on the slave is > 255 bytes. '
The patch also includes the needed changes to unpack to ensure that data
which is smaller on the master can be unpacked correctly on the slave.
Problem: mysqlbinlog_base64 failed sporadically.
Reason: Missing "flush logs" before running $MYSQL_BINLOG,
which could start dumping the log file before server
has finished writting into it.
Fix:
- implementing --force-if-open option to "mysqlbinlog"
- adding --disable-force-if-open to make $MYSQL_BINLOG
fail on non-closed log files, to garantee that nobody
will forget "flush logs" in the future.
- adding "flush logs" into all affected tests.
"mysqldump" test fails (mysqlimport related, Brian aware), ndb_cache2 ndb_cache_multi2
partition_mgm_err fail (unrelated to my changes), rpl_row_view01 (known crash BUG#17265)
